Customer service to understand the leakage switch and air switch for our daily use of electricity is still very helpful. Below, Nanyang Xiaobian for everyone to see what is air switch, what is leakage switch.

What is an air switch?

Air switches are also called air circuit breakers. The principle of the air switch is to use air as an insulating medium, to turn on the current in the circuit, to make the component generate heat, and to make the bimetallic strip bends up when it is heated up, and to push the lever to open the locked button and cut off the power supply, so that the air switch will automatically trip itself to achieve a protective current. Generally, the automatic tripping is due to the overload of the circuit, or short circuit problems. The opening of the lock is a lever device. The lever can make the lock open and achieve the purpose of automatic tripping. Compared to the air switch and the leakage switch, the air switch is more complicated in principle.

What is a leakage switch?

Leakage switch, as its name implies, is a kind of switch to prevent leakage and cause safety accidents. The principle of the leakage switch is that it has a small chip in its center. There are two things called windings, one main and one pair. The main winding is divided into two windings, that is, the output and the input current winding. If there is no leakage, the output current is equal to the input current, so that the vector of the two flux on the chip is zero, and there will not be any safety accidents on the windings. Once the principle is deviated from the principle, the secondary winding will generate electric pressure, drive the built-in mechanism, and finally automatically trip. In principle, this is one of the differences between the air switch and the leakage switch.
